I know, I just wanted you to be aware of it. The list can be found on Marineland's website. This was recently updated a few weeks back to include more model numbers. Earlier it didn't include the 50w (which I assume you have for a 10g?)
Anyways here is the link...http://www.marineland.com/update.aspx

I think it may be. I can check again against that last, but I bought the heater a couple months before xmas, so I don't think it's one of the recalled ones. I'll check again though if the list has been updated.

Edit: 8| Welp. Guess it's off to petsmart again or something, idk. Need to figure out who to cxalls as mine was bought in MN, and I'm in MI now.
